Playing Firestorm Game ...I am receiving this error message before login.
"We are unable to decode the file storing your saved login credentials. At this point saving or deleting credentials will erase all those that were previously stored. This may happen when you change network setup. Restarting the viewer with previous network configuration may help recovering your saved login credentials."
I have removed the game completely from my laptop the correct way, and downloaded a fresh, clean version, but this message is there again...i have played this game since 2013 with 3 new Macs...did not have this problem before. I am not techie, so an answer will need to be rather simple for me...thanks!
MacBook, Mac OS X (10.6.8)
